The gross similarity index of 43% is reduced to allow for the
similarity
contributed by the cover sheet. The net similarity is 34% (still
too high to
be acceptable).
Use high quality references. Wikipedia or blogs may be useful to
gain a
quick insight, but the quality of the content will be uncertain
as it is often
unverified. Adapted from Academic Integrity Handout_4Nov13

Some Key Points
Interpret Similarity Index
High/Low SI does not automatically indicates high/low level of
plagiarism
Judgement needs to be made based on content knowledge
SI does effectively set off alarms, raising the concern and
calling for attention/correction
Innocent/Coincidental Matches
Common phrases and set forms used in essays or reports
Direct quotations
References or bibliographical materials
Resubmitted report after revision
Similarities caused by these matches need to be
excluded or ignored in assessment
